Abstract |
Seventeen patients who were diagnosed as primary hypophosphatemic rickets at Department of
Pediatrics, Seoul National University Children’s Hospital were analyzed to assess its clinical aspect
and effect of treatment, especially on height and growth velosity.
The average age of onset was 2 years, and their chief complaints were bowleg and short stature.
Sex ratio was l.l:l(male: female). Familial hypophoshatemic rickets was known as X-linked domi-
nant inheritance, however, majority of patients (7.4〜5.2%) in this study were sporadic cases. Their
height was near or below 3rd percentile. With treatment their growth pattern was found to be
pararrel to normal growth curve, and catch up growth (height gain) was not observed in majority, but
early treatmnet in earlier age facilitated growth velosity and height and catch up was observed in a
few patients.
On an appropriate therapy with Vitamin D (8427 IU/kg) for 11 months, though phosphate level was
not changed, serum alkaline phosphatase was notably decreased below 300IU/L of therapeutic level.
We observed two patient whose serum alkaline phosphatase rebounded back during growth spurt at
puberty when additional further increment of vitamin D was required. In all patients on appropriate
treatment, x-ray findings of rickets revealed marked improvement. |
